TO ALL WHOM IT MAY CONCERN:

Be it known that I, DARIUS WELLNGTON,`of Boston, in the county ofSuffolk, and State of Massachusetts, haveinvented an ImprovedBrick-Machine; and I do hereby declare that the following, taken inconneetion with the drawingswhich accompany and form part of thisspeoiieatiomis a description of my invention suliicient to enable thoseskilled in the art to practise it. i

My invention relates to an organization of mechanism for converting clayinto bricks for burning, and the invention consists in the peculiarcombination and arrangement of parts by which the crude' clay, afterbeing divided and pulverized in a pug-mill, is fed from thence into aseries of moulds, automatically and successively K v brought under andfed vfrom the mill, and is solidified in the moulds and ejected fromthem, the surface of the mould, after being filled, being passed under acutter, which cuts off the clay in the mould from that above it, andthen under a throat-piece, which presses the loose clay into anyunfilled parts of the mould, and then under a scraper, which smooths thesurfaces of the bricks, and scrapes all projecting pieces or edges ofclay from the mould.

The drawings represent a machine embodying my invention- A showing aside elevation, and A B a vertical longitudinal section of the same. y adenotes a strong bed, supported on a suitable frame, and extendingnearly from end to end of the machine. Over thisbed is erected apulveriaing-mill, b, in' which is a vertical rotary shaft, c, carrying aseries of inclined blades, d, which, in their rotation, not onlydividoor break up the crude clay entered at the mouth of the mill,

but press it downwards towards the bed.

This shaft is supported i-n a bearing, e, on the framework above the beda, and carries at its foot a bevelgearf, which meshes into and is drivenby a bevel-pinion, g, on'the driving-shaft h.

At the lower part of the mill, a stationarywing, z',`stretchos acrossfrom the hub or bearing e to each side of themill, and the pulverizedmaterial pressed down by the blades dis stopped from further rotation bythese wings, and collecting against them, is caught by the upper edge ofa screw-blade, k, bounded by a ring or cylinder, l, this screw-blade, inits rotation, pressing the clay down against and into the mouldsbeneath.

The moulds m m traverse over the top surface of the bed a, and betweensuitable guides or ways, which keep the moulds' in position as' theyslide over the bed. v i

The moulds tpinto a square opening, u, and drop through the same on tothe bed a. In'rcar of this opening is a reciprocating plate or follower,o, the front end of which, as the follower goes back, comes under andflush with the rear wallp, allowing an empty mould to drop through theopening udown upon the bed.

' As the follower goes forward, it pushes tile mould before it, so as tocarry said mould just from under the opening and sliding it from underthe mould, resting upon it, which mould falls down upon the follower,and

-when the follower next goes back, falls down in front of it upon thebed a, its movement forward, by the next forward movement of thefollower, carrying thc mould, inadvance of it, under the mill, where therotation of the screw-blade fills it with clay.

The follower is attached to slides, g, on opposite sides of the machine,and these slides are connected by connecting-rods r to gearedcrank-wheels, s, meshing into and driven by a pinion-gear, t, on thedriving-shaft. The shaft of the crank-wheel is so hung that when theconnecting-rods are moving forward to advance the follower and moulds,they are in line with the slides q, and thereby prevent that strain uponthe slides and follower which would takc place were the connectionotherwise made.

The mould under the mill being filled, it is pressed forward by theempty mould next in rear of it, and as it moves on, it passes under a.scraper, t', which cuts the clay in the mould o from the mass vof clayabove. This leaves the mould charged, except on its sides, where theclay may not ll out closely, or may be drawn back as the mould movesunder the scraper. Ithereforo place an'inelined throat-piece, u, infront of the scraper, and as the loose clay above the mould hugs downunder `this throat-piece, it is again compressed down snare 2 againstthe mould, and ii'lls all inter-sticos `left therein, an adjustableknife or .doctor, y, then trimming -oi allsurfaee clay as the mouldpasses under it.

The filled mould passes beyond the d octor, and is brought-to a state ofrest (as the follower@ moves back) directly under avertieallyreciprcating plunger or compresser-block, o. This block and adischarge-block orl piston, ze, are xed to the under surface of aplaten, x, at the opposite ends of which are fixed slide-plates a',having vertical slots b', throughl which project guide-screws e.

To each plate aisjointed a. lever, dturnin'g on a fulerum, e',and'earrying at itsrear end a`pinf, pro. jecting into accom-groove, g',on the inner face of the gear-wheel 8,'the cam-groove being concentricwith the axis of the gear, excepting in that part thereof acting uponthpin, while'the follower o is retreating and the moulds are at rest. ic

l As the follower rst begins to retreat, the cam forces the adjacentendofthe lever up, and thereby depresses the `opposite end, earryingtheblock e down into the lled mould beneath it, and compressing orsolidifying the clay in the mouldfthe block being raised bythe continuedaetionjof the cam as the follower completes its retreat.

The next forward movement of the follower carries the mould with thesolidified clay underthe dischargeblock w, where it stops (as thefollower retreats) while the discharger w descends. Thisrforwardmovement of the mould carries it'beyond the bed clover ,which it has.previously slid through all its intermittent movements) on t side rails7L', leaving the mould open at its under surface. The discharged plungerthen descends, and

ejects the clay from the mould in the form of av smooth,compaet, solidbrick, the bricks falling upon an eud' less apron, i', by which they maybe conveyed to any desirable locality for drying. l

The next forward movement of the moulds pushes oif the empty mould,which is then returned to the mouth or opening n to bc refilled. i l

The mechanism organized substantially as shown, .may be vused in theconversion of peat into portable blocks for fuel, as well as for themanufacture of bricks. i

` I claim, in combination with the follower, (which intermittently feedsforward the series of moulds,) and with the rotating pulverizing-blsdcsd and feed-screw c, (which break up the clay and force it into themoulds,)

I the scraper-bart', the throat-piece u, and the doctor y, each arrangedto operate substantially as set forth.

Also, in combination with the reducing and feeding-mill b, and with themould-feeding mechanism, the solidifying-plungerv, and expelling-plungerw, when arranged to operate substantially as described.

' Also, the arrangement of" the bevel-gcarf, at the bottom of thepulverizing aud'mould-iilling mill 6, to be driven by'a pinion, g, onthe driving-shaft, just above the bed a, substantially as described.

Also, the arrangement ofthe crank and cam-wheel s, connecting-rod r,slides q, lever d', and slide-plates a', for driving the follower o andpluugers e w, substantially as described.
